SPECIFICATION forming part of Letters Patent 2l.\1'0.351,837I dated November 2, 1886.

Application filed May 8, 1885. Serial No. 164,7;15. (No model.)

T0 all whom t may concern:

Be it known that I, EDWIN S. LENox, a citizen ofthe United States, residi ng at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Machinery Plant for Producing Wire Rods; and I declare the following to be a description of my said inventionv sufficiently full, clear, and exact to enable others skilled in the-art to which it apper'tains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

The object of my present invention is to provide, in combination with rolls for making wire rods, an apparatus for taking care ofthe overfeed of the rod intermediately of the rolls to obviate the necessity of allowing the rod to loop out upon the iioor or table; to provide,

l tinuous operation through the series of reducing-rolls at intermediate stages between the reducing-rolls in a wire-rod-rolling mill; to provide, in combination with a mill for working wire rods, av revolving receptacle into which the wire rod can be introduced and from which it may be drawn automatically, which receptacle isv adapted for preventing the rod from becoming tangled by reason of the overfeed of the leading-rolls in excess of the following-rolls, and for retaining the heat of the rod during the operation. Theseobjects I attain by mechanism the nature, construction, and operation of which is illustrated in the drawings and explained in the following description, the particular subject-matter claimed being hereinafter definitely specified.

In thedrawings, Figure l is a vertical sectional view showing one form of my improved receiver and so much of a rolli ng-,mill for making wire rods as is necessary to illustrate the nature of my invention. Fig.Y 2 is a plan view of the same. Fig. 3 is a vertical sectional view showing a modified construction of the receiver and guides, and in which the receiver showing the fin-repressing rolls, Vand Fig. 6 is a transverse section at line g/ y on Fig. 4.

In reference to parts, A denotes the leading or primary rolls, and B denotes the followingrolls, which may be the rolls in any style of rolling-millV for making or working wirerods. C indicates a revoluble vessel or receiver for containing the overfeed of the Wire rod as it comes from the leading-rolls A, having a central funnel-shaped opening at c, through which the rod can pass to the guides D d, which conduct it direct to the pass of the following-rolls B, which may be for reducing the section or for removing the fins on the rod.

' The receiver C may be of any suitable form and mounted with its axis of revolution either vertical, horizontal, or inclined. ent instance, in Fig. l, Ihave shown a receiver of conical form having curved sides and mounted with its axis of revolution inan inclined position. `Said receiver is supported. by a bearing at @,and by anti-friction rolls E,which run on a guide about the periphery of the receiver. Suitable gears, G, and driving-shaft G are provided for effecting the rotary motion of the` receiver. The driving-gearing may be arranged in anyconvenient manner to be operated from the same motor that drives the rollingmill, or either section thereof, or the receiver may be rotated by separate driving apparatus, as preferred. The rod is led into the receiver from the leading-rolls A by a guide, F, which directs the rod in such a manner that its advance end will pass direct through the opening C and guides D to the following-rolls B automatically. Said guide may be made with a curved end, f, and .mounted in a bearing, H, in such a manner that the guide can be rotated or moved to direct the rod more or less toward the side of the receiver, a handle, h, being provided for effecting the adjustment of the guide F after the end of the rod has entered between the following-rolls B. A roll, D', Inay be arranged in the guide D, as indicated, for changing the direc- In the prestion of the rod and for preventing friction as the rod is drawn from the receiver. The month of the receiver may be closed by a cover, I, to assist in retaining the heat of the rod, said cover being supported as indicated in Fig. l by dotted lilies, or in other suitable manner.

The operation of my improved apparatus is as follows: The rod coming from the rolls A shoots through the guide Fte the bottom of the receiver, and lthence through the passage c and guides D d to the rolls B direct and automatically; or, in some instances, provision may be made for seizing the end of the rod as it issues :from the passage c or guide D and entering it to the rolls by an attendant, in which latter case a greater distance would be allowed between the guides D and d. The overfeed or surplus of the rod, due to the speed of its delivery from the rolls A in excess of the speed at which it is taken by the rolls B, re sults in t-he looping out of the rod within the receptacle C, and the rotary action of said receptacle causes the overfeed of the rod to arrange itself in a series of coils against the walls of the receiver, the coils being increased at the top as the rod is fed in, while the coils from the bottom are at the same time drawn ont as the rod passes to the rolls B.

In some instances it may be desirable to make the receiver in the modified form shown in Fig. 3, or more nearly in the form of a fiattened plate, mounted on a vertical axis to revolve in a horizontal plane, with a funnelshapcd opening, c, in the center for the passage of the rod to the following guides and rolls. This form of receiver permits the overfeed of the rod to Vextend ont in a series of spiral coils, gradually increasing in extent as the amount of overfeed increases; or, again, the receiver may be made of cylindrical form with a funnelshaped end and passage, c, as in Fig. 4. This latter form of receiver may be arranged in line with the rolls at both front and rear, and the rod be fedi nto it direct from the primary rolls or from the guide F, as indicated. Said cylindrical receiver may be revoluble or non-revoluble, with the guide F arranged revoluble in bearings H H, and provided with a driving-pulley, P, or other means for effecting the rotation thereof. The end f of the guide being at one side of the axis of rotation, delivers the rod into the receiver with awinding or spiral action. Vith the form of receiver shown in Fig. 3 the rod might, in some instances, if desired, be fed to the receiver by a revolving guide in similar manner to that of Fig. 4, the receiver being non-rotative, or rotated at a different rate of speed, as most convenient.

In some cases it may be desirable to form the passage c, through which the rod is withdrawn from the receiver, at other position than central with the axis of revolution 5 and I do not therefore confine myself to a receiver having a central passage, as said passage may be at any position where most convenient for drawing out the coils at one end of the series while fresh coils are being laid in at the other end of the series, so that the rod is both passing in and out ofthe receiver at the same time.

A receiver into which het wire rods can be projected and from which said heated rod can at the same time be withdrawn, as above set forth, may be employed between any of the several pairs 01 sets of rolls through which the rod passes in the course of its reduction or manipulation for taking care of the overfeed of the rod and maintaining the heat thereof; and said receivers are ot' especial utility where the rod becomes considerably attenuated, and the speed of delivery is very great, as it permits ofthe speed of the latter rolls being considerably lessened, while it practically preserves the rod in condition to be rolled down to a coniparatively small size.

In Figs. 4 and 5 I have shown a set of iinrepressing rolls, K, in combination with the receiver C, for correcting the form or section of the overstocked ends or portions of the rod as it comes through the exit-passage e ot' the receiver. Said rolls are made in a set of four rolls, (three might be used, if preferrech) thc combined grooves of which form a pass of the required size and shape of tlie rod at this stage of its reduction. Said rolls act upon the rod directly as it comes from the receiver, and as the tins are made by rolls working in pairs, while the ii-iepiessing rolls are in aset ot' four, fitting together as shown, giving a different bearing and spacing from the pair, they act to reduce the tins in whatever way the end of the rod may be presented to them.

The receiver C may be used in a rollingmill plant having a single primary train of rolls and two supplemental trains, in which case two receivers would be employed, and a switching-guide would be required between the rolls A and the guide F, that conducts the rod into the receiver C, so that rods could be alternately directed to the right or left receiver. In such case the plant might be disposed with thejsupplemental trains at right angles to the primary train, and the switch-guide be made on a curve, or one-quarter are of a circle, so that ahalf-revolution oftheguide would change the direction in which the rod is projected from the right to the left, and vice versa.

In some instances it may be desirable to increase thc heat of the rod while it is passing through the receiver. This may be accomplished by the use of gas applied in connection with the receiver in any suitable manner; and such use andadaptation I reserve the right to embrace in a separate application for Letters Patent.

Vhat I claim as of my invention, and desire to secure by Letters Patent, is-

l. The combination, with the rolls in a rolling-mill for making wire rods, of aI receiver for containing the overfeed of the rod, cornprehending a bowl or interior chamber within which the slack of the rod can be thrown into spiral coils, and tapering at its delivery end to an exit-passage, through which the rod can be TIO IIS

withdrawn from said receiver While it is' being fed into the same from the rolls ofthe mill, substantially as set forth.

2. In` a plant for making wire rods, the comchamber is caused to assume a spiral order as the rod is passing into and out of said receiver, substantially as set forth.

3. In a plant for making wire rods, the combination, with the working-rolls, of a revoluble receiver having a funnel-shaped opening, through which the rod can pass to the following rolls while it is being fed into said receiver from the leading-rolls, substantially as and for the purpose set forth.

4. In a plant for making Wire rods, the cornbination, withtwo sets of rod-w0rking rolls, of an intermediately-located vessel or receiver having an exit-opening for the withdrawal of u the rod` at one end thereof and a revoluble delivery-guide for directing the rod into said receiver at the other end thereofas it issues from the leading set of rolls, substantially as set forth.

ythe apparatus, substantially as set forth.

5. The combination, substantially as de- 3o scribed, of two or more sets of rolls,a receiver for containing-the overfeed, having a funnelshaped passage for the exit of therod, a rotatable curved or inclined guide for delivering the rod from one set .of rolls to the interior of 35 said receiver, andv guides for directing the rod from the exit-passage of said receiver t0 the pass of the following set of rolls,whereby said rod may be automatically conducted through 6. The combination, substantially as described, of a set of reducingrolls, a receiver for containing the overfeed of the wire rod, provided with an exit-passage through which to withdraw therod while it is being fed thereto from the rolls, and a set of nrepressing rolls disposed for acting upon the rod as it issues from said exit-passage, as set forth.

7. The combination, substantially as described, of the primary rolls A, the guide F, the receiver C, the guide D, and roll D', for the purposes set forth.
